Ratings and Reviews
Superb
I’ve been using this app for well over a year as a daily driver and I don’t have a single bad thing to say about it!
The natural language layout mirrors the best scientific calculators on the market, but with the flexibility of a smartphone the functionality is vastly superior.
The communication between myself and the developer during beta testing is top-notch with fast turnaround for bug squashing as well as helping to implement UI improvements & new features!
The attention to detail and build quality is well worth me recommending this app to anyone reading this review.
Developer Response ,
Glad you're enjoying the app, and thank you for taking the time to review - it really helps out! 😄
in case you do indeed need a calculator on a regular basis, don't look any further!
Why choose this calculator over any other in AppStore:
(1) It is most versatile, while not trying to emulate a classical hardware calculator (like «15C Scientific Calculator», probably the best application of this kind in AppStore), nor offering useless frills for those in permanent need of entertainment. In short, it is for those who do indeed need …well, a calculator, without the illusion of holding one in ones' hands.
(2) The developer does not harvest nor sells any of your data. In the meantime this respectful attitude towards one's users has become quite rare. I am very thankful for this.
(3) The developer offers his application for free, and leaves it to each user's sense of decency to put some money into the «tip jar», or not.

2 years later:
(a) I continue to like this well designed app, but Jacob Parker (the developer) does now collect «Diagnostics». How much this is linkable to an identity is everybody's guess.
(b) there is no way to leave a second tip for Jacob. This is, of course, a AppStore decision, to discourage developers strenghten their relations with their users. I have no reason to assume that Apple allows oversights, neglects glitches.
(c) the size of the TechniCalc window cannot be changed! This is really strange, but I have seen this also before, mainly in applications developed in Germany. It is beyond me, why some developers, like Jacob, go out of their way to disable resizing windows, which is something so basic to expect.
–––
Maybe I should clarify point (c) above: I expect to be able to resize the TechniCalc Calculator like any other macOS window, by dragging-and-dropping a any of the four corners of its unique window. I hope this clarification helps.
(d) I resent not being able to just e-mail the developer Jacob Parker, and I am obiged to join some social medium to communicate with him. What is wrong with just e-mailing?
Developer Response ,
Thank you! 🤩
For the 2 years later update - I do now collect crash logs and crash logs only. They’ve really helped! No personal data is included, you can email me and I can share some logs if you’re interested - I’ve got nothing to hide! I’ll look into why you’re restricted to tipping once. I had no idea! And on macOS you can resize the window between the compact and large size - just like the built in calculator. Hope this helps!
